How to Deal with the Noise from the Sunroof of the Tiguan?
3 Answers
Tiguan sunroof noise should be divided into two states: when the car is moving and when the car is stationary. Here are the details: 1. When the car is stationary, if there is noise when opening or closing the sunroof, the main problem lies with the sunroof itself. It may be due to insufficient lubricant on the sunroof slide rails or dust and other foreign objects on the rails. In this case, regular maintenance and inspection of the sunroof slide rails are necessary to keep them clean and lubricated. 2. When the car is moving, if there is noise with the sunroof closed, it may be caused by loose bolts securing the sunroof to the car body. In this case, simply tightening the bolts will resolve the issue.
The sunroof rattle on the Tiguan is really annoying, and I’ve experienced it myself. At the time, I tried inspecting it myself and found that the tracks were clogged with dust and leaves, causing squeaking noises when opening and closing. I carefully cleaned the tracks with a damp cloth and applied a specialized silicone-based lubricant, which immediately made it much quieter. If lubrication doesn’t solve the issue, it might be due to loose screws—tighten the screws on both sides of the sliding track with a hex key. Additionally, worn-out seals can also cause friction noises. I noticed fine cracks on the seals and sprayed them with rubber protectant to extend their lifespan. If the sunroof frame is deformed, it’s best to have a professional adjust it. Try to avoid parking under trees to prevent debris from falling into the tracks.
To fix the Tiguan sunroof noise, find the root cause. First, open the sunshade to locate the sound. If it's from the tracks, use a vacuum to remove debris and dust—this is crucial. Last time, I bought special sunroof lubricant, sprayed it around the tracks, and the squeaking stopped. If it only rattles on bumpy roads, it’s likely loose screws—remove the headliner to tighten the rail screws. A low rustling sound suggests aging seals; just spray rubber conditioner. Avoid solvents like WD40, as they can corrode rubber. If all else fails, visit the dealership to check for bracket deformation. Lubricate the tracks every six months as a preventive measure.
